Subtle flicker in the dimmest color while data is being transferred #1

Closed Effix closed 8 years ago

There is subtle flicker in the dimmest color while data is being transferred. At first I though it was just interference between the OE pwm and the pixel brightness duty cycle, but it goes away if the front buffer is just left to continuously display.

This is most noticeable with the brightness lower than 50%.

It actually does not go away when idling on the front buffer...

Changing the passes per frame to 8 (by changing the default hold timings from 1, 4, 4 to 1, 3, 4) helped this at almost all brightness levels.
